Fall Prep & Winterizing — September to October

One cracked fitting costs more than the whole kit

Water left in a pump, a tankless heater or a low point line freezes, expands and splits it. Spring then starts with a flooded floor. Prepare before the first freezing temperatures in your area; timing varies by location and storage conditions.

The job, in order

1. Drain — fresh tank, water heater, low-point drains. Water heater bypass valve — view current price so antifreeze doesn't fill the heater.
2. Blow out or bypass — RV Winterizing Kit with blowout adapter — view current price, or 3-way pump converter kit — view current price to pull antifreeze through the lines.
3. Protect the battery — a lithium bank sitting at 100% or 0% for four months ages fast. Victron Blue Smart IP65 charger — view current price on storage mode, or disconnect and store at 50–60%.
4. Cover it — Silver Trailer Cover for Black Series — view current price.
5. Seal against drafts and pests — foam, vent covers, faucet cover for the outside shower.
